Can I invest using an IRA?
You may use your IRA to invest. Just specify that you are investing as a IRA instead of as an individual during the investment process by checking the box labeled "I want to invest as a non-person legal entity such as a company, trust, or self-directed IRA" towards the bottom of the investment form.
It won't be as an ACH--it has to be either a check or wire, depending on how the IRA company sends funds. You will need to request it from the IRA as they will be the vesting entity. We'll be sent funds that say something like: Big IRA Company, Custodian for (or FBO), sometimes they add an account number.
